My Hackintosh started freezing after booting (Sonoma, BIOS 9i). I searched this thread before posting the message.
I haven't changed anything recently (no new kexts, hardware, other upgrades). The system used to work fine until it didn't.
Things I've tried (that didn't help resolving the issue):
1. Reset NVRAM
2. Boot into recovery and run First Aid
3. Boot into backed up Catalina on a separate drive - it worked fine (ran First Aid there too just in case)
4. Restart/hard restart/turn off the machine many times (obviously)
PS. I have Windows on a separate drive that I can boot from OpenCore - it works fine, no issues.
Any ideas or suggestions? Like I mentioned, I've made no changes to the system whatsoever, no I have no idea what happened or how to fix this.
PPS. I think that I saw this happening the first time after I sent my machine to Sleep from Windows; then when after a few hours I "woke" the machine and tried loading Sonoma from OC bootloader, that's when the "disaster struck".
